While I agree that the pads used can impact rotor lifespan, people need to get ready to shell out for new rotors when they take their car in for their 2nd brake job.
If they wait for sounds from the brakes, they will likely be replacing them at the next change, regardless of mileage. That noise you hear is the sound of your rotors being scarred, likely beyond what machining the rotor can remove.
